    "summary": "This case report describes a 40-year-old man with an intramuscular schwannoma in the left tensor fasciae latae muscle, located where he habitually kept his smartphone in his front left trouser pocket. Imaging (ultrasound, elastography, MRI) characterized the lesion, and the authors note the mass location corresponded to the phone's SIM card position. The authors do not claim causality but speculate the storage habit could be a predisposing factor and call for further research.",

        "A single intramuscular schwannoma case is reported in the left thigh.",
        "The lesion location coincided with the patient’s habitual smartphone storage site (front left trouser pocket).",
        "Ultrasound showed a well-defined encapsulated hypoechoic lesion with small foci of vascularity on Doppler.",
        "Elastography indicated deformability score 2 with some stiff areas.",
        "MRI confirmed a spindle-shaped mass with varying enhancement after contrast.",
        "The authors state causality cannot be established and the proposed link is speculative.",
        "The paper calls for further research on potential health risks of smartphone storage habits."
